Low fermentation temperatures (∼10 °C) favor the synthesis of fruit esters, such as isoamyl, isobutyl and hexyl acetates, whereas higher temperatures (15–20 °C) promote the production of higher-molecular-weight esters, such as ethyl octanoate, ethyl decanoate, and phenethyl acetate (Killian and Ough, 1979). 225 0 obj <> 178 0 obj endobj <> 283 0 obj 221 0 obj Linear Formula CH 3 COOCH 2 CH 2 CH(CH 3) 2.
